Matters needing attention on glass grating
- Apr 10, 2018 -

1. Because of the low density and light weight, it is easy to install the glass steel grille in the higher ground water level, so it is necessary to consider the anti-floating measures such as the setting of the town pier or the drainage of rainwater.

2, in has been shipped on glass fiber reinforced plastic grille tee, repair pipe crack, etc, the construction requirements completely dry conditions similar to the plant and construction of resin and fiber cloth still need 7-8 hours curing, and site construction and repair of generally difficult to meet this requirement.

3, existing underground pipeline detection equipment mainly detect metal pipeline, and nonmetal pipeline detection instrument is expensive, therefore unable to detect after buried FRP gratings, other easily in the subsequent construction units in construction injury, damage to the pipe.

4. Poor uv resistance of glass steel grille. The glass reinforced plastic grating can delay the aging time by making 0.5mm thick resin layer and ultraviolet absorbent (processing) on its surface. As the running time, the rich resin layer and ultraviolet absorbent will be destroyed, thus affecting their service life.
